IMPROVEMENT IN WATER-ELEVA-TORS.

Specication forming part of Letters Patent No.'l7,339, dated February13, 1877; application filed October 23, 1876.

l'o all whom it may concern:

Be it known that I, ALEXANDER WRIGHT, of Havana, Cuba, have invented anew and Improved Steam-Pump, of which the following is a specification:

The accompanying drawing represents a vertical longitudinal section ofmy improved steam-pump.

The invention relates to an improved steampump for raising water by thedirect action of the steam, in analogous manner asin steaminjectors; andthe invention consists of a steam-pipe with a nozzle, seated in aperforated casting submerged in the water, and drawing in and raisingthe Water through a tapering spout and wider exitpipe by the action ofthe steam.

In the drawing, A represents a steam-conducting pipe, which ispreferably placed within an outer pipe, and surrounded by coal-ashes orother non-conducting material, to prevent condensation.

The steam-pipe A is bolted, by a face-plate, a, to a flanged casting, B,of cylindrical or other shape, so as to be readily detached therefrom,for changing without removing the casting from the seats. The casting Bis submerged into the water, and made of two flanged sections, which arejointed together, one section supporting, in suitable bearings, thenozzle C, that connects with the steampipe A; the other sectionsupporting in similar manner a tapering collar or spout, D, through thecontracted opening of which the Water is drawnA through perforations bof the nozzle-section, and forced, by the action of the steam, into thewider discharge-pipe A. The exit-pipe A is attached, by a face ring orplate, d, binding on the flanged rim of the pipe, to the opposite end ofthe casting B, so as to be changed with the same facility as thesteam-pipe.

The principle on which the pump Works is analogous to that ofsteam-injectors, the action ofthe steam producing a partial vacuum andcreating a suction, that draws in the water to be raised, forcing itforward and upward to any height through the water-discharge pipe.

The pump may also be used with advan tage as a bilge-pump on board ofSteamers, the construction being simple and effective for this purpose.

Having th us described my invention, I claim as new and desire to secureby Letters Patent- Y A steam-pump made of a submerged sectional casting.of which one section is perforated, and provided with a nozzle andsteamsupply pipe, while the other section has a tapering collar or spoutand wider water-discharge pipe, substantially in the manner and for thepurpose set forth.
